SEPARA'IOR-GUARD.

Specification of Letters Patent.

Application filed July 5, 1912.

Patented Oct. 7, 1913.

Serial No. 707,929.

To aZZ whom it may concern.

Be it known that I, ARTHUR W. Pirrs, citizen of the United States, residing at Bonham, in the county of Fannin and State of Texas, have invented certain new and useful Improvements in Separator-Guards; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to separator guards for spinning frames, and the invention consists in the provision of novel means for preventing the yarn from being entangled in or caught by the devices for attaching the separators to their support.

In the accompanying drawings forming part of this application, Figure 1 is a fragmentary View in perspective showing a portion of a ring spinning frame, the separators and the guard adjacent thereto. Fig. 2 is a front view of the separator bar, with the separators attached. Fig. 3 is a side view of one of the separators, with an end view of the bar.

In Fig. 1 the ring spinning frame is indicated by 10, the rollers by 15, and the yarn guides by 16. The separators 20 are mounted on a separator bar 21, in the manner described below. The spindles are designated 25, the traveler rings 26 and the traverse bar 27.

It is well understood that the separators 20 are designed to prevent the excessive ballooning of the yarn due to the high speed of the spindles. While the separators are essential on this account, they are ordinarily attached in such manner that the screws or attaching devices are practically in the path of the thread or yarn, frequently causing breakage. Broken pieces of yarn may be seen under the heads of the screws on all machines in use, and the aggregate loss on this account amounts to a large sum.

In order to overcome the difficulty men tioned I provide a device 30 which projects from the bar 21 and extends beyond the heads of the screws. This device acts as a screw guard and yarn guide and prevents the engagement of the screws by the yarn. The separators 20 are provided with ears 31 which are slotted at 32, the screws passing through the slots and the washers 88, said ears engaging a flanged portion 3 1- of guard 80, as shown in Fig. 3, as well as in Fig. 2. The securing devices of the separators are thus effectively shielded from the yarn.

The separators are partly supported by devices 30, as will be seen in Fig. 3.

It is obvious that the device described may be attached to any machine now in use, and that other means of carrying out the invention may be resorted to, within the scope of the appended claim, the essential feature being the provision of means for keeping the yarn from the securing devices and con fining it to a given path with reference to one side of the bobbin, while the separators themselves define the path of the yarn on adjacent sides of the bobbin.

What I claim as new and desire to secure by Letters Patent is:

In a device of the class described, a yarn winding device, an upper yarn guiding device, a bar located below the latter, yarn separators carried by the bar, means for securing the separators to the bar, said seouring means permitting of the adjustment of the separators and projecting laterally from the front of the bar, between the separators, and means extending from each separator to the adjacent separator and serving to partly support the separators and to guide the yarn away from the securing means.

In testimony whereof I affix my signature in presence of two witnesses.

ARTHUR W. PITTS.
